Windows 7: WU error 80070002, sfc /scannow blocked?

26 Mar 2017   #1

Windows 7 Home Premium 64bit
WU error 80070002, sfc /scannow blocked?


My Windows Update service has been defunct for some time now, and I've finally decided to create an account to try and see if I can be helped. I've creeped on this forum for about a year now trying to solve this issue without any luck and decided it was time to make my own thread. Here we go...

When attempting to use Windows Update to search for updates I get the error code: "80070002"

Attempts to run: "windows6.1-KB976932-X64.exe" or
(both being Service Pack 1 for Windows 7 x64) result in "ERROR_FILE_NOT_FOUND(0x80070002)" messages.

sfc /scannow
While using an elevated command prompt, attempts to run "sfc /scannow" or "sfc /verifyonly" result in an identical error message: "Windows Resource Protection could not perform the requested operation."

However, when searching the CBS.log file, I can't find any errors with an "SR" tag on them (I read somewhere that this tag was specific to SFC issues). I even tried the following line in the command prompt to make a text file of the relevant errors...

< findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" >

But the command resulted in an empty sfcdetails.txt file being created on my desktop.

Trying to run the "sfc /scannow" or "sfc /verifyonly" in safemode or safemode with a command prompt resulted in the same error message as above.
Trying to run the "sfc /scannow" or "sfc /verifyonly" in "repair mode" boot results in an error message saying something about how the command couldn't be completed due to a repair being active and a restart needing to occur first (presumably being in repair mode was preventing the sfc /scannow command from running?

I've also completed a chkdsk /r which came back with no bad sectors.

Also ran the System Update Readiness Tool for Windows 7 for x64-based systems (Windows6.1-KB947821-v34-x64.msu). Logs do seem to have identified some issues, but I don't have a clue about what to do next.

Please find the CBS file attached to this thread.

Please advise.

Hi Tyler,
can you copy/paste the results of this tool,

If it comes back clean, it will be quicker and easier for me to provide you with a W7 SP1 link.

I'm guessing that since that same error code I've been getting (0x80070002) popped up all over the assessment that you had me run that this means that the report didn't come back "clean"?

Also, small sidenote, you mentioned that Windows Defender is not a complete AV software. Can you point me to a non-biased website discussing what good options I would have for AV coverage? Especially lightweight and free options?

Hi Tyler,
Nothing fundamentally wrong with the report

However, your BIOS seems to be corrupted and the likely cause of the update failures.
It appears that its been changed at some stage, possibly for the Office install.
(even if i supply an W7 SP1 it wont update!!.)

You will need to update your Bios from MSI for that motherboard
I will NOT guarentee this will work because of the changes you have made previously, and it may even totally brick your machine

Proceed at your own risk
after updating your bios, and removing Office, you may find updates appearing.
If not repost the tools new output.

Hi Roy,

A corrupted BIOS might actually make a lot of sense because this system has suffered from, what I thought to be, a separate issue of my computer failing to boot and producing a BSOD every other time that I boot the machine (booting after the computer has been at rest for 1 or more hours tends to result in a failed boot, but booting within a few minutes of a recent shut down tends to result in a successful boot). This has been an issue that I've had for years, and have spent countless hours trying to track down the origin, even taking it into a professional computer repair store which was unable to identify the issue.

Regarding your feedback I had a couple questions:

1. What should I do to better assess the likelihood that attempting to update the BIOS will "brick" my machine? The idea of 'bricking' my machine is terrifying to me and I'd like to take any reasonable precautions available to prevent this.

2. I assume that I should make sure that everything on my HDD is backed up onto other storage devices before attempting the BIOS update?

3. Should I remove Office before or after doing the BIOS update?

4. Are there any other viable options for resolving my issue without risking a BIOS update and, therefore, possibly 'bricking' my system?

Thanks for all your help,

Hi Tyler,
I was being generous as your OS is showing as genuine.

There is a Bios hack on your system presumably for the Office install, its coming back as non-genuine, by the way.
I suspect that its causing ALL your problems.

As i have absolutely NO idea what changes were made by it, and hacks are not my area, all i can do is make guesses, hence my previous comment--

Uninstalling Office should not brick your system but updating the bios could.
Most definately back-up your drive

All i can do is wish you luck, if you update it

Hi Roy,

Something is wrong here, because I am certain I never (intentionally) installed a BIOS hack, especially not one for Microsoft Office. My copy of Office was provided to me by my university several years ago; I have the verification key sitting in a box in my closet. I just now went into Office Word and confirmed that my copy of Office is "Activated" (if that is relevant). I'm really at a loss here for why that diagnostic would come back as indicating my system has a non-genuine version of Office...

I don't understand how a BIOS hack could have been installed onto my system... Is there anything else that could cause the diagnostic to indicate that (e.g., power fluctuation, bit-flip, failed BIOS update)? I do remember updating the BIOS with a flash drive several years ago, but I imagine that I would have only installed something from the appropriate source (i.e., the motherboard manufacturer, MSI), so I don't believe that it would have been the result of inaccurate or malicious original code accidentally being used to update my BIOS.

Most importantly, does this (my attestation that I never installed a BIOS hack) change my recommended course of action in any way?

Thank you,

Hi Tyler,

Been researching, should shed more light on your problem as its quite rare.
Your motherboard comes either OEM or Retail, this is where it gets interesting
If MSI overstocked on the OEM side they moved them to Retail,
BUT then they had to change/flash the Bios to remove the OEM identifiers--
Now if they did this it would show as a Hack, EVEN if the OS was legitimate, as in your case.

What then would happen is that when Windows/Office, checks for updates/patches they fail
(excluding security ones, and identify office as non-genuine).
Now as SP1 was released in 2010, when did you build yours??, it should have installed years ago!

The activation side of things covers more than one stage,
can you install KB971033

rerun the tool, then copy/paste me todays CBS log - zip not rar its allready on your comp
